Southern Sierra Nevada Fractional Land Cover 2014 - 2018

Creator:: McGregor, Eric L., Green, Rebecca E., Purcell, Kathryn L., Tucker, Jody M., Matthews, Sean M., and Green, David S.
Abstract:: This dataset is designed to capture landscape changes brought on by a severe tree mortality episode in California's southern Sierra Nevada range, by mapping multiple land cover types in a continuous way at annual time-steps throughout the mortality event. By mapping multiple land cover types we can see not only...

Land Cover Classification (5-meter) - Kings River Fisher Project 2014 - 2018

Creator:: McGregor, Eric L., Purcell, Kathryn L., Green, Rebecca E., Matthews, Sean M., Green, David S., and Tucker, Jody M.
Abstract:: These high resolution (5x5-meter pixel) categorical models of land cover were created by training random forest classification models on RapidEye (Planet Labs Inc.) satellite spectral data for each year and then predicting those models across the landscape. Training data were created by visually interpreting random plots over high resolution NAIP...

Use of created snags by cavity-nesting birds across 25 years

Creator:: Barry, Amy M., Hagar, Joan C., and Rivers, James W.
Abstract:: Snags are important habitat features for many forest-dwelling species, so reductions in the number of snags can lead to the loss of biodiversity in forest ecosystems. Intentional snag creation is often used in managed forests to mitigate the long-term declines of naturally created snags, yet information regarding the use of...

Experimental brood enlargement differentially influences the magnitude of the corticosterone stress response in closely related, co-occurring songbirds

Creator:: Hardt, Braelei M., Ardia, Daniel R., Bashaw, Meredith J., and Rivers, James W.
Abstract:: 1. Rearing environments can shape offspring phenotype across taxa, yet little is known about how brood size influences hypothalamic-pituitary axis functioning, whether its expression trades off with growth, and the degree to which these -relationships vary between species. 2. We evaluated how brood size influenced nestling physiological (glucocorticoids) and somatic...

Wild bee diversity is enhanced by experimental removal of timber harvest residue within intensively managed conifer forest

Creator:: Rivers, James W., Mathis, Codey L., Moldenke, Andrew R., and Betts, Matthew G.
Abstract:: The use of timber harvest residue as an energy source is thought to have environmental benefits relative to food-based crops, yet the ecological impact of this practice remains largely unknown. We assessed whether the abundance and diversity of wild bees (Apoidea) were influenced by the removal of harvest residue and...

River restoration practitioner survey on engineering design for climate change

Creator:: Tullos, Desiree
Abstract:: An online survey of river restoration practitioners, engineers, and researchers was conducted to examine current practices and perspectives on how climate change is integrated into engineering designs for river restoration. Seventy-six responses were submitted to the survey. While the responses came from a wide range of demographies, respondents were most...

A catchment-scale assessment of stream temperature response to contemporary forest harvesting in the Oregon Coast Range

Creator:: Kevin Bladon, Nicholas Cook, Jeffery Light, and Catalina Segura
Abstract:: Historical forest harvesting practices were reviewed in the original Alsea Watershed Study where they found increased energy loading to the stream and produced higher stream temperatures. This was an important early research site that led to the development of contemporary forest management practices to protect water quality and fish habitat...

Daily Snowpack Fate Data Supporting New Metrics for Snow in a Warming Climate: Indicators for the National Climate Assessment

Creator:: Hu, J. Michelle
Abstract:: Snowpack impacts and trends in precipitation regimes are investigated for the mountainous western United States from water years 1984–2016. The vast majority of snow trend studies utilize undifferentiated air temperature records, which do not segregate between days with and without precipitation and effectually dilute temperature trends relevant for snowpack monitoring....

Snowpack Contributions and Temperature Characterization of Landfalling Atmospheric Rivers in the Western Cordillera of the United States

Creator:: Hu, J. Michelle
Abstract:: This study utilized long-term daily precipitation and snow-water equivalent (SWE) data derived from the Natural Resources Conservation Service’s Snow Telemetry Network (SNOTEL). All existing SNOTEL sites in the Olympic, Coast and Cascade ranges in Washington (n = 66) and Oregon (n = 52) and in the California Sierra Nevada (n...
